Title: Hadronic production of W and Z bosons at large transverse momentum

Abstract

We propose a modified factorization formalism in quantum chromodynamics for hadronic production of W and Z bosons at large transverse momentum p T . When p T is much larger than the invariant mass Q of the vector boson, this new factorization formalism systematically resums the large fragmentation logarithms, α s m ln m ( p T 2 / Q 2 ) , to all orders in the strong coupling α s . Using our modified factorization formalism, we present the next-to-leading-order (NLO) predictions for W and Z boson production at high p T at the CERN Large Hadron Collider and at a future 100 TeV proton-proton collider. Our NLO results are about 5% larger in normalization, and they reflect improved convergence and moderate reduction of the scale variation compared to the NLO predictions derived in a conventional fixed-order perturbative expansion.
